Template not using my custom stylesheet?

So I was removing the right hand modules from my OC install, and no matter what I tried, the middle content would refuse to stretch over. I discovered that the reason for this is because OC wasn't using my custom stylesheet, it was still using the default stylesheet, even though it was quite clearly using my theme in the admin panel.

Is this a bug? Where is the CSS file designated?

Edit: It's also using the images of the default theme.

Check your stylesheet include in header.tpl.

Ah, that did it. Thanks.

Whut? I think I found a bug in your spelling

You are indeed a comical fellow. Well done.
